GATE.

Application filed September 11, 1922. Serial No. 587,625.

To all whom/15 may concern j Be it known that I, JOHN MoCoRMroK. acitizen of the Dominion of Canada, and resident of Ottawa, in the countyof Carleton and Province of Ontario, Dominion of Y Canada, have inventedcertain new and use ful Improvements in Gates, of which the fol* lowingis a specification.

This invention has rela-tion to certain new anduseful improvements ingate structures and has for its primary object the provision of a gatestructure which will be of simple and inexpensive construction and whichmay bc readily opened, if desired, from a distance thereof.

The invention has for another object the provision of a gate which willbe automatically locked when closed but which may be readily unlocked orunlatched and opened by the operation of a single rock shaft controlledby levers on opposite ends thereof at a considerable distance fromeither side of the gate. j

A further object of the invention resides inthe provision of a gate ofthe character stated, which willv be of such construction that thelongitudinal bars thereof will swing on their rear ends and move towardand away from one another at their forward ends as the gate is openedand closed.

The invention has for a further object the provision of a gate of thecharacter stated in which will be included a novel form of latchreleasing mechanism connected with and controlled bythe rockshaftcarrying the gate lifting'or opening members, so that the gatelatch will be thrown into inoperative position at the beginning of theoperation `of the. rock shaft which opens the gate. 1

The invention has for a still further object the provision of a gate ofthe character set forth, which will be composed of the minimum number ofparts of simple and inexpensive construction yan arrangement, which willbe strong andsubstantial, highly efficient in use and which will includea the gate.y

when approaching the gate from either side Y balancing member'adjustably mounted on- Vith the foregoingjand other objects in view,ceeds as will appear as the description prothe invention consists inthenovel construction, combination and arrangement of co-operating elementsas hereinafter more specifically set forth, claimed and shown in t-heaccompanying drawings forming a part of the present application, inwhich:

Fig. 1 is an elevation of the improved gate in closed position, the gatebeing indicated in partially open position by dott-ed lines.

Fig. 2 is a plan view of the gate in closed position.

Referring more in det-ail to the drawings, 1n which similar referencecharacters design ate corresponding parts throughout the several views,5 indicates the latch carrying g and carries the link 6 which is ofsubstanf ate post which is slotted longitudinally tially U-shaped formand pivotally mounted e at the free ends of its legs on the pivot mem-`lower inwardly directed end ofthe depending` latch member 8 engagesupon the upper face of the projecting forward end 9 of one of .th

the central bar, as shown in Fig. 1.

e longitudinal gate bars 10, preferably The projecting forward end 9 ofthis longitudilatch `nal gate bar 10 extends through the latch carryinggate closed position.

A' substantially 11 is post 5 when the gate is in U-shaped bracingmember extendedover theupper portion of the carrying gate post 5 andmounted on 1 the pivot. members 12 on opposite sides thereof. It willtherefore be seen that while the substantially U-shaped bracing member11 serves to brace the latch carrying gate post will not interfere withopening and closing of the gate, as the substantially U-shapedbracingmember 11 may be turned away from the lugs.'

gate, as shown in the drawe gate' post lf3' is at the other side of thegate opening and is anchored in upright position, as will be seen byreferring to Fig. 1. The inclined gate carrying post 1-1 is connected atits upper end to the upright gate post 13, as shown in the drawings andext-ends downwardly and forwardly from one side thereof, as will bereadily understood by referring to Fie'. 1. The inclined gate carryingpost 14 is formed of parallel spaced members vconnected at their upperends by the connecting bolt 15.

The connecting members 16 extended through the forward end of thehorizontal post bracing member 17 arealso extended through the lowerportions of the spaced members forming'the inclined gate carrying post1i. Suitable connecting members 18 are passed through the rear end `ofthe horizontal post bracing-member 17 and into the lower portion of thegate post 13, as shown, clearly in `Fig. 1. It is therefore evident thatth'ehhorizontal post bracing member 17 serves to connect and rmly bracethe gate post l?) and the inclined gate carrying post 14.

The several longitudinal gate bars are mounted on their/rcspectiye pivotbolts 19 which extend through the rear ends of the longitudinal gatebars 10 and through the spaced members of the inclined gate carry- 'ingpost 111 to permit the longitudinal gate bars V10 to swing in a verticalplan from the inclinedgate carrying post 14. The several longitudinalgate bars 10 are connected near their forward ends by the parallelconnecting bars 20 positioned on opposite sides of the. gate andextending downwardly and forwardly with the lower ends of said parallelconnecting bars 2O `depending below the bottom or lowermost longitudinalgate bar 10. Pivot bolts 21 are extended through the parallel connectingbars 20 andthrough the respective longitudinal gate bars 10, as showninthe drawings. By referring to Fig. 1. it'will be evident that theparallel connecting bars 20 permit the longitudinal l gate bars 10 toswingfreely on their respective pivot bolts 19 and as the gate swingsupwardly, the forward free ends of the longitudinal gate bars 10 willmove closer toether, as indicated by dotted lines.

The reinforcing plates 22 are `secured upon the sides ofthe lowermostlongitudinalgate bar 10 at the rear end thereof, as shown clearly inFig. 1. `Similar reinforcing plates 23 are secured on the sides of theuppermost longitudinal `gate bar 10 and mountedV on; the gate operatingshaft 24 extended transversely through vthe inclined gate-carrying post'14 in lplace of a pivot bolt 19 for this uppermost longitudinal gatebar 10. y Therear end of the uppermost longitudinal gate'bar 10 is cutaway, as shown in Fig. 1 and the v purpose of which will presentlyappear.

By referring to Fig. 2, it will be seen that the gate operating shaft 24extends for some distance to either side of the gate and thenIterminates in downwardly directed operat ing ends 25. It will also beseen by referring to Fig. 2 that the reinforcing plates 23 have theirmain portions offset outwardly from the sides of the longitudinal gatebars 10 and positioned outwardly of the sides of the inclinedgatecarrying post 14. This is also true of the reinforcing plates 22, asshown in Fig. 2.

Rigidly mounted on the centre of the gate yoperating shaft'24t is theupwardly and rearwardly directed lever arm 26, to the upper end of whichi'spivotally connected one end of therod 27,`the other or forward end ofwhich is pivotally connected to the upper end of the latch releasinglinger 28. This latch releasing finger 28 is mounted on the pivot bolt29 provided 'therefor in the 'forward end portion of the uppermostlongitudinal gate bar 10, while the downwardly and outwardly directedlower end 30of the latch releasing fingerv 28 worlts freely through thelatch vcarrying gate post 5. This downwardly and `outwardlydirectedlower end 30 of the latch 'releasing finger 28 engages the inner sideofthe depending latchfmember 8 to force the same outwardly toinoperative position and release the ygate when the latch releasingfinger'28 isfoperated through the medium of the rod 27 and upwardly andrearwardly directed lever arm 2G when the .gate operating shaft 24: isturned in one direction.

Rigidly mounted on the gate operating shaft 24E, outwardly of the sidesof the inclined gate carrying post 14 and adjacent thel latter,.-are thegate raisingmembers 31 which are inclined doivnwardly and `forwardly andthen extended forwardly in a Ahorizontal plane. as shown clearly in Fig.1.

Thesegate raising members `terminate in turned 'forward free endsdirected toward one another and extending` beneath vthe-reinforcingplates 23 and normally spaced slightly below the same.

lVhen turning ofthe .gate operating shaft 211 is continued after lthereleasing of `the depending latch member 8` from the gate, theturnedforward free ends 82 of the 'gate raising members 31 will contact withthe reinforcing plates 23 and raise the 'gate to open positionbyrswinging the longitudinal gate bars10 upwardly on their pivotallymounted rear ends. This maybe readily understood'by reference to Fig. 1.in which the gate is shown by dotted lines in partially 'open position.

Tn order that the gate may be properly balanced at allt'imes andlopening and closing 'thereof more readily accomplished, acounterbalanoing weight 33 is employed. This counterbalancing weight 33is adjustlll) ably "mounted between the extended rear ends of thelongitudinally slotted weight supporting bars 53a by means of themounting members adapted to be secured in adjusted position along theslots of the -longitudinally slotted weight supporting bars 231i. y

One of the central or inner longitudinal gate bars 'l0 carries thelongitudinally slotted weight supporting bars 34 which areslidablymounted on the pivot bolt 19 for said longitudinal gate bar l()and a clamp ing` nut 3G is employed on an additional guide bolt 37projecting from one side of the said longitudinal gate bar lO andthrough the slots of the longitudinally slotted weight supporting barsSe, so that the latter may be securely fastened in adjusted positionhingitudinally of the longitudinal gate bar l0.

It is evident that a line adjustment of the (.:ounterbalancing weight 38on the gate may be accomplished by adjustment of the counterbalancingweight 323 on the longitudinally slotted weight supporting bars 34: andalso adjustment of the latter on the longitudinal gate bar l supportingthe same, Downward swinging movement of the gate is limited by means ofa stop block 38 within the latch carrying gate post 5.

From the foregoing pay 1agraphs taken in connection with theaccompanying drawings, the complete construction and operation should beapparent. It may be briefly stated, however, that Whenever the gate isclosed7 the depending latch member 8 will automatically engage theprojecting forward end 9 of one of the longitudinal gate bars 10 andlock or latch the gate in closed position; as shown in F l.

lllhenever it is desired to open the gate when approaching the same fromeither direction; the downwardly directed operating end Q5 of lthe gateoperating shaft 24 on this side of the gate is grasped and the gateoperatingY shaft 24 rotated or turned in the proper direction to drawback thevupwardly and rearwardly directed lever arm 26 and actuate thelatch releasing finger 28 to disengage the dependinglatch member 8 andswing the saine together with its link 6 on the pivot members 7 untilthe depending operating ends and as the gate closes, the depending latchmember 8 will automatically catch upon the projecting forward end 9 ofone of the longitudinal gate'bars l() and again latch or lock the gatein closed position. l

lVhile the preferred embodiment of the intention has been disclosed, itis to be understood that minor changes in the details of construction,combination and arrangement of co-operating elements may be resorted towithin the scope of what is claimed without departing from the spirit ofthe invention.
